FLOOD SIMULATIONS IN RESPONSE TO THE CLIMATE CHANGES IN CENTRAL, VIETNAM Quan Van Dau, MSCE Department of Civil Engineering, Khon Kaen University, Khon Kaen, Thailand Kittiwet Kuntiyawichai, PhD Assistant Professor, Department of Civil Engineering, Khon Kaen University, Khon Kaen, Thailand ________________________________________ Abstract: Flood is a natural feature of the environment and is also one the most frequent hazardous natural disaster. The impacts of flood are highly devastating
blocked photosynthesis in plants thus breaking multiple food chains. Acids rain would have been present killing plants and poisoning water sources and killing off certain species that live in water. Carbon dioxide would have been released causing global warming which would have continued even after the dust cleared and the acid rain washed away. Evidence of anoxia is also found as well as euxinia (hydrogen sulphide). These two phenomena are believed to have killed off most of the marine life of this
1 INTRODUCTION Ethiopia is not only a country dominated by agriculture; it is a country of smallholder farmers. The livelihood decisions of this predominant farming community are largely constrained by diminishing land availability, declining soil productivity, the marginaliza-tion of time-tested crops, poor access to technology and the volatility of agricultural mar-kets (Fenta and Ali 2003). In a society so reliant for survival on agricultural land with few other livelihood options, these constraints
The term global warming refers to a gradual increase in the average temperature of the earth and its oceans; it is an adaptation that is believed to be permanently changing the earth's climate. Scientists are trying to tell us that the planet is warming. The increased amount of carbon dioxide and other greenhouse gases released by the burning of fuels, agriculture, and other activities, are considered to be the foremost sources of the global warming that has occurred over the past decades. In the
affected the habitat of flora and fauna. Besides that, the clearance of forest has forced the animals to shift from their natural habitat so they will face difficulties to survive and tends to extinct. Increase in Global Warming Trees play a major role in controlling global warming as the trees utilize the greenhouse gases, restoring the balance in the atmosphere. Deforestation
of the most socially responsible companies in the world. They have lowered their carbon emissions and have used solar power to fuel more than 600 of their sites. They have also raised their corporate standard to be aligned with the United Nations Global Compact. They are also uniquely one of the first companies in the world to have tied employee salary and bonuses to the company’s environmental and social responsibility
Climate Change Climate change – To What extent is man’s responsible for an increase in global temperature? The world’s climate is changing, and the changes will have an enormous impact on our planet’s people, ecosystems, cities, and energy use. Also, Global warming may affect the average global air temperature is already 1.5 degrees to 0.15 degrees due to carbon emission. However, the changes could be significant with its small but dispersed in the future. Most experts and researches have proved
atmosphere carbon dioxide, which is causing gradual global warming. This is called the ‘greenhouse effect’ and is responsible for the increased average global temperatures. Such climate change adversely impacts every country, including Bangladesh. Stephen Hawking, the world’s most famous physicist, recently in an interview warned about the ultimate consequences of denying climate change. He stated that ‘we are close to the tipping point where global warming becomes irreversible.’ Denying climate change
in atmosphere this could take us over the tipping point which may make us lose control over the climatic chaos that might unfold as a result of this. The other scientists only confirm the facts that the global warming is not an anticipated phenomenon we have already increased the average global temperature by about one degree and are likely to continue to increase it further by a few more degrees. The phenomenon across the globe like icebergs belting, sea level rising, hurricanes becoming stronger
Overpopulation There was around 3.5 billion people added to the population between 1950 and 2000.This was the fastest growing rate people have ever seen.”The world's population in the year 2006 was estimated to be over 6.5 billion people in the world strong and growing” ().The problem with so many people is that everything will start to overpopulate. Some solutions are that we can number a family on how much kids the could have. Another solution is that they could also try not to produce as much
